Abstract Objective : To understand the type of dietary patterns in the women during pregnancy and the distribution characteristics of children's birth weight and the association between dietary patterns and neonatal birth weight in Shaanxi, China. Methods: Data were derived from a cross-sectional program named “The prevalence and risk factors of birth defects in Shaanxi Province” in July to November in 2013. A stratified multistage random sampling method was used to select women , according to the urban-rural ratio and taking into account the population intensity and fertility level, 10 urban districts and 20 counties were randomly selected. In the sample counties, 6 townships were randomly selected (3 districts in the urban area), and 6 villages were randomly selected from each township (6 communities in the urban districts), each village randomly surveyed 30 (60 in the community) women whose latest dates of pregnancy were during January 2010 to November 2013 and their children. The mother's diet during pregnancy was investigated using semi-quantitative food frequency questionnaire to collect the frequency and amount of food consumption, and the newborn birth weight as well as related social demographic information was collected at the same time. This study selected children aged between 0-1 years old and their mothers with complete dietary survey data as the study subjects. The main dietary patterns were identified according to factor analysis, and latent class analysis (LCA) was used to investigate the social demographic factors affecting dietary patterns. The logistic regression model was used to investigate the association between birth weight and maternal dietary patterns during pregnancy by establishing three adjusting models and the data were stratified for further analysis by urban-rural and regions. Results : Totally 15980 participants were involved in this study, and the birth weight was 1050-6250g (3279.9±454.6). There were 783 newborns with birth weight of <2500g, accounting for 4.9%; and 703 newborns with birth weight >4000g, accounting for 4.4%. The incidence of SGA and LGA was 14.7% and 7.6%, respectively.Factor analysis was used to extract four dietary patterns during pregnancy: "vegetarian pattern", "balance pattern", "traditional pattern" and "processing pattern". The vegetarian pattern was a predominant pattern. LCA analysis indicated that urban women preferred to choose the balance pattern and rural women preferred for the traditional pattern. The balance pattern and processing pattern were the main ones in the southern region, the vegetarian pattern in the northern region and the traditional pattern in the middle region. Further study on the association between dietary patterns and neonatal birth weight, founding that the vegetarian pattern was positively associated with a higher risk of low birth weight in rural areas and middle region, and the traditional pattern was a risk factor for the occurrence of low birth weight in the middle region. The processing pattern was found a protective factor for the occurrence of low birth weight in rural areas but was a risk factor for low birth weight in the southern region. The balance pattern was a protective factor for the occurrence of low birth weight in the northern region. Conclusion : There are four kinds of dietary patterns in the pregnant women of childbearing age in Shaanxi Province, "vegetarian pattern" is predominant, and the dietary structure needs to be improved. The vegetarian and traditional pattern may be positively related to a higher risk of low birth weight while the balanced pattern may keep birth weight of offspring within the appropriate range. Health education of balanced diet and individual nutrition guidance during pregnancy should be strengthened, in order to make dietary structure during pregnancy are more reasonable, reduce the occurrence of adverse birth weight of newborns.

Abstract Objective To examine the type of maternal dietary patterns during pregnancy and the distribution characteristics of children’s birth weight and the association between dietary patterns and neonatal birth weight in China. Methods Data were derived from a cross-sectional program named “The prevalence and risk factors of birth defects in Shaanxi Province” in July to November in 2013. A stratified multistage random sampling method was used to select women and their children. The mother’s diet during pregnancy was investigated using semi-quantitative food frequency questionnaire (FFQ) to collect the frequency and amount of food consumption, and the newborn birth weight as well as related social demographic information was collected at the same time. In our study, 0–1 year old children and their mothers with complete dietary survey data were selected as research objects. The main dietary patterns were identified according to factor analysis, and latent class analysis (LCA) was used to investigate the social demographic factors affecting dietary patterns. The logistic regression model was used to assess the association between birth weight and maternal dietary patterns during pregnancy by establishing three adjusting models and the data were stratified for further analysis by urban-rural and regions. Results A total of 15,980 participants were involved in this study. Four dietary patterns were identified: “vegetarian pattern”, “balance pattern”, “traditional pattern” and “processing pattern”. Compared with moderate tertile, women in the highest tertile of adherence to vegetarian pattern increased the risk of low birth weight in offspring in rural areas (OR = 1.61, 95%CI:1.06–2.93) and middle region (OR = 1.75, 95%CI:1.18–2.62), and the traditional pattern had greater odds of lower birth weight in the middle region (OR = 1.55, 95%CI:1.05–3.75). The processing pattern was found a protective factor for the occurrence of low birth weight in rural areas (OR = 0.98, 95%CI:0.43–0.99) but was a risk factor for low birth weight in the southern region (OR = 8.83, 95%CI:1.22–15.16). The balance pattern was a protective factor for the occurrence of low birth weight in the northern region(OR = 0.35, 95%CI:0.14–0.83). Conclusion The vegetarian and traditional pattern may be positively related to a higher risk of low birth weight while the balanced pattern may keep birth weight of offspring within the appropriate range. Health education of balanced diet and individual nutrition guidance during pregnancy should be strengthened, to make the dietary structure during pregnancy are more reasonable, reduce the occurrence of adverse birth weight of newborns.

Abstract Objectives To explore the effect of iron supplementation during pregnancy on neonatal birth weight in childbearing aged women in Shaanxi province. Methods A sample of 24,952 women of childbearing age (18 ∼ 49) living in Shaanxi province of China who gave birth in 2010–2013 were surveyed using a stratified, multistage and random sampling method. The information about their characteristics were recorded by a structured questionnaire. Multiple linear regression model and quantile regression model were employed with the birth weight of newborns and gestational iron supplementation as dependent variables and independent variables respectively, and controlling confounding factors. Results Among the 24,952 women of childbearing age surveyed, multiple linear regression and quantile regression analysis showed that the birth weight of newborns whose mothers had iron supplementation during pregnancy were significantly higher than those whose mothers had no iron supplement during pregnancy from very low to higher percentiles (q = 0–0.35, q = 0.80), an average increase of 38.31 g (β = 38.31, t = 2.99 and P &lt; 0.01). With the increase of the percentiles of birth weight, the birth weight of newborns increase declined gradually in those whose mothers had iron supplementation compared with those whose mothers had no iron supplementation. Conclusions Supplementation of iron during pregnancy can increase the neonatal birth weight, which has a greater effect in newborns with lower body weight than in newborns with higher body Weight.

Control Study

Objective To evaluate whether the presence of maternal blood pressure reduces the risks of morbidity, perinatal mortality and morbidity at 24 months of age in very low birth weight infants (VLBWIs) compared with a control group. Methods A retrospective, observational, case-control study. Total 49 VLBWIs were allocated to the study group, called the maternal arterial hypertension group (AHG), and matched with 44 in the control group (CG). The infants were assessed during hospitalization and at 12 and 24 months corrected age at a specialized clinic. For the assessment of growth, the World Health Organization (WHO) Anthro software (Geneva, 2006) was used, and for the psychomotor assessment, the Denver II test was used. Results In relation to the antenatal variables, the infants of the AHG had more centralized circulation assessed by Doppler, received more corticosteroids and magnesium sulfate, and were born by cesarean section more frequently. In terms of the postnatal and in-hospital outcomes, the AHG had a higher gestational age at birth (30.7 versus 29.6 weeks) and a lower frequency of 5-minute Apgar scores of less than 7 (26.5% versus 52.3%). The CG had a higher rate of pulmonary dysplasia (30.2% versus 8.3%). There were no differences in terms of hospital mortality, complications, somatic growth and functional problems at 24 months of corrected age. Conclusion The presence of maternal hypertension, especially preeclampsia, was not a protective factor against morbidity, mortality and evolution in VLBWIs aged up to 24 months. Therefore, the clinical practice should be focused on prolonging the pregnancy for as long as possible in these conditions as well.

BACKGROUND Low birth weight (LBW) is a common outcome of preterm birth and increases the risk of an infant’s morbidity and mortality. About 20 million infants are born with low birth weight globally. Since a significant number of births in Pakistan take place at home, it is important to focus on the use of Kangaroo Mother Care (KMC) (skin-to-skin contact) in communities to prevent neonatal mortality and morbidity. OBJECTIVE We conducted a formative research in order to understand the context of communities and facilities with regards to neonatal care and KMC practice, inform the design and delivery of culturally appropriate platforms to introduce KMC in communities, and develop effective recruitment and retention strategies of KMC, in rural areas of district Dadu, in the Sindh province. METHODS We conducted focus group discussions, in-depth interviews and key informant interviews with families of LBW babies, community members, healthcare providers and hospital administrators to identify barriers, enablers and a knowledge base for KMC interventions. RESULTS Newborn care practices in communities were subpar. Although KMC practices are not commonly practiced in communities and facilities and the method is unknown to many, family members were willing to provide KMC to LBW babies to improve their health outcomes. Community members, hospital administrators and healthcare providers widely accepted the practice for neonatal health and found it feasible and convenient. CONCLUSIONS The KMC as a method of treating low birth weight babies is widely accepted in the community. This formative research provided strategically effective ways for developing effective implementation strategies by identifying common community practices for LBW babies, and barriers and enablers to KMC practice.

Fundus Pigmentation

Objective. A prospective study design was used to investigate the association between different degrees of fundus pigmentation and the incidence of retinopathy of prematurity (ROP) among very low birth weight infants in a large neonatal intensive care unit. Methods. The study group consisted of 161 infants weighing 1500 g or less at birth and included all infants born from 1988 to 1990 who survived at least 10 weeks. Presence or lack of any acute stage ROP was determined by weekly ophthalmological examination from the age of 4 weeks. The degree of fundus pigmentation was recorded for each infant during the first examination. Results. Infants with dark fundus pigmentation were found to be at half the risk of developing ROP as compared with the infants having light/medium fundus pigmentation (relative risk 0.5;95% confidence interval = 0.2-1.1). When controlling for birth weight, gestational age, length of oxygen therapy, and ethnic group in multivariate analysis, dark pigmentation was an independent and statistically significant protective factor (odds ratio = 0.09, 95% confidence interval = 0.02-0.6). None of the infants with Stage III ROP or higher had dark pigmentation. Conclusion. We speculate that large amounts of melanin in the retinal pigment epithelium or choroid may protect the dark-pigmented very low birth weight infant from developing ROP.

ObjectivesThe present study aimed to estimate the prevalence of low birth weight (LBW), and to investigate the association between maternal body weight measured in terms of body mass index (BMI) and birth weight in selected countries in Africa.SettingUrban and rural household in Burkina Faso, Ghana, Malawi, Senegal and Uganda.ParticipantsMothers (n=11 418) aged between 15 and 49 years with a history of childbirth in the last 5 years.ResultsThe prevalence of LBW in Burkina Faso, Ghana, Malawi, Senegal and Uganda was, respectively, 13.4%, 10.2%, 12.1%, 15.7% and 10%. Compared with women who are of normal weight, underweight mothers had a higher likelihood of giving birth to LBW babies in all countries except Ghana. However, the association between maternal BMI and birth weight was found to be statistically significant for Senegal only (OR=1.961 (95% CI 1.259 to 3.055)).ConclusionUnderweight mothers in Senegal share a greater risk of having LBW babies compared with their normal-weight counterparts. Programmes targeting to address infant mortality should focus on promoting nutritional status among women of childbearing age. Longitudinal studies are required to better elucidate the causal nature of the relationship between maternal underweight and LBW.

ObjectiveThis study is concerned with helping to improve the health and care of newborn babies in Bangladesh by exploring adverse maternal circumstances and assessing whether these are contributing towards low birth weight (LBW) in neonates.Study designs and settingsData were drawn and analysed from the Bangladesh Demographic and Health Survey, 2014. Any association between LBW and adverse maternal circumstances were assessed using a Chi-square test with determinants of LBW identified by multivariate logistic regression analysis.ParticipantsThe study is based on 4728 children aged below 5 years and born to women from selected households.ResultsThe rate of LBW was around 19.9% (199 per 1000 live births) with the highest level found in the Sylhet region (26.2%). The rate was even higher in rural areas (20.8%) and among illiterate mothers (26.6%). Several adverse maternal circumstances of the women included in the survey were found to be significant for increasing the likelihood of giving birth to LBW babies. These circumstances included the women being underweight (adjusted odds ratio (AOR) 1.26, 95% CI 1.06 to 1.49); having unwanted births (AOR 1.22, 95% CI 1.03 to 1.44); had previous pregnancies terminated (AOR 1.28, 95% CI 1.05 to 1.57); were victims of intimate partner violence (AOR 1.23, 95% CI 1.05 to 1.45) and taking antenatal care <4 times (AOR 1.23, 95% CI 1.03 to 1.48). Other important risk factors that were revealed included age at birth <18 years (AOR 1.42, 95% CI 1.11 to 1.83) and intervals between the number of births <24 months (AOR 1.25, 95% CI 1.01 to 1.55). When taking multiple fertility behaviours together such as, the ages of the women at birth (<18 years with interval <24 months (AOR 1.26, 95% CI 1.02 to 1.57) and birth order (>3 with interval <24 months (AOR 1.68, 95% CI 1.18 to 2.37), then the risk of having LBW babies significantly increased.ConclusionThis study finds that adverse maternal circumstances combined with high-risk fertility behaviours are significantly associated with LBW in neonates. This situation could severely impede progress in Bangladesh towards achieving the sustainable development goal concerned with the healthcare of newborns.
